erogeneous equilibria. a. 2NBT3(s)=N2(g) + 3Br2(g) b. CuO(s) + H2(g) Cu(I) + H20(g) c. 4Fe(s) + 3O2(g)=2Fe2O3(s) 17-7 Le Châtelier's Principle Questions 29. In your own words, describe what Le Châtelier's principle tells us about how we can change the position of a reaction system at equilibrium 0. Consider the reaction 2CO(g) + O2(g)= 2CO2(g) Suppose the system is already at equilibrium, and then an ad- ditional mole of CO(g) is injected into the system at constant temperature. Does the amount of CO2(8) in the system increase or decrease? Does the value of K for the reaction change? 31. For an equilibrium involving gaseous substances, what effect, in general terms, is realized when the volume of the system is decreased? 32. What is the effect on the equilibrium position if an endothermic reaction is carried out at a higher temperature? Does the net amount of product increase or decrease? Does the value of the equilibrium constant change if the temperature is increased? Problems 33. For the reaction system C(s) + H2O(g) H2(g) + CO(g) which has already reached a state of equilibrium, predict the effect that each of the following changes will have on the posi-Explanation / Answer
30)
Adding reactant will shift the reaction in the direction of product as per Le chatelier Principle
So, Adding CO2 moves Equilibrium to product side
This increases the concentration of CO2
Since temperature is constant, value of K will not change
value of K doesn’t depend on concentration
Answer:
CO2 increases
K do not change
